Issue is related to the NETCONF library underpinning PyEz. We have been getting around this issue by continuing to use Python 3.11 until ncclient has an update, which was completed in the last few days.

ncclient/ncclient#572

Opened a PR to bump the dependency and resolve the issue.

#1277

In addition to #1277, this repo also needs to update the vendored versioneer.py for the same reason as the linked ncclient issue: #1278

It would be more than awesome to run this software on the current Python software (3.12) instead of 3.9 or older which is nearly EoE: https://devguide.python.org/versions/

PyEZ support python 3.10 and above
